* | r8152: reduce the control transfer of rtl8152_get_version()Hayes Wang2023-01-201-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | Reduce the control transfer by moving calling rtl8152_get_version() in rtl8152_probe(). This could prevent from calling rtl8152_get_version() for unnecessary situations. For example, after setting config #2 for the device, there are two interfaces and rtl8152_probe() may be called twice. However, we don't need to call rtl8152_get_version() for this situation.

The r815x family devices expose a vendor specific function which the r8152 interface driver wants to handle. This is the preferred device mode. Additionally one or more USB class functions are usually supported for hosts lacking a vendor specific driver. The choice is USB configuration based, with one alternate function per configuration.

Using the above example, Linux defaults to cfg #2, running the device in a sub-optimal NCM mode. Previously we've attempted to work around the problem by blacklisting the devices in the ECM class driver "cdc_ether", and matching on the ECM class function in the vendor specific interface driver. The latter has been used to switch back to the vendor specific configuration when the driver is probed for a class function. This workaround has several issues; - class driver blacklists is additional maintanence cruft in an unrelated driver - class driver blacklists prevents users from optionally running the devices in class mode - each device needs double match entries in the vendor driver - the initial probing as a class function slows down device discovery Now these issues have become even worse with the introduction of firmware supporting both NCM and ECM, where NCM ends up as the default mode in Linux. To use the same workaround, we now have to blacklist the devices in to two different class drivers and add yet another match entry to the vendor specific driver. This patch implements an alternative workaround strategy - independent of the interface drivers. It avoids adding a blacklist to the cdc_ncm driver and will let us remove the existing blacklist from the cdc_ether driver. As an additional bonus, removing the blacklists allow users to select one of the other device modes if wanted. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S.

* | treewide: Convert del_timer*() to timer_shutdown*()Steven Rostedt (Google)2022-12-251-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to several bugs caused by timers being re-armed after they are shutdown and just before they are freed, a new state of timers was added called "shutdown". After a timer is set to this state, then it can no longer be re-armed. The following script was run to find all the trivial locations where del_timer() or del_timer_sync() is called in the same function that the object holding the timer is freed. It also ignores any locations where the timer->function is modified between the del_timer*() and the free(), as that is not considered a "trivial" case. This was created by using a coccinelle script and the following commands: $ cat timer.cocci @@ expression ptr, slab; identifier timer, rfield; @@ ( - del_timer(&ptr->timer); + timer_shutdown(&ptr->timer); | - del_timer_sync(&ptr->timer); + timer_shutdown_sync(&ptr->timer); ) ... when strict when != ptr->timer ( kfree_rcu(ptr, rfield); | kmem_cache_free(slab, ptr); | kfree(ptr); ) $ spatch timer.cocci . > /tmp/t.patch $ patch -p1 < /tmp/t.patch Link: https://lore.kernel.org/lkml/20221123201306.823305113@linutronix.de/ Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org> Acked-by: Pavel Machek <pavel@ucw.cz> [ LED ] Acked-by: Kalle Valo <kvalo@kernel.org> [ wireless ] Acked-by: Paolo Abeni <pabeni@redhat.com> [ networking ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | The RX FIFO would be changed when suspending, so the related settings have to be modified, too. Otherwise, the flow control would work abnormally.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are 2 models for MV32 serials. MV32-W-A is designed based on Qualcomm SDX62 chip, and MV32-W-B is designed based on Qualcomm SDX65 chip. So we use 2 different PID to separate it.

* Revert "net: usb: ax88179_178a needs FLAG_SEND_ZLP"Jose Alonso2022-08-101-13/+13
| | | | | | | | | | | | | | | | | | | | This reverts commit 36a15e1cb134c0395261ba1940762703f778438c. The usage of FLAG_SEND_ZLP causes problems to other firmware/hardware versions that have no issues. The FLAG_SEND_ZLP is not safe to use in this context. See: https://patchwork.ozlabs.org/project/netdev/patch/1270599787.8900.8.camel@Linuxdev4-laptop/#118378 The original problem needs another way to solve.
